摘要： PURPOSE: To reduce the number of parts, to simplify the structure, to make the thickness smaller, and to improve the reliability by successively forming the 1st colored layer, a diffusion layer and the 2nd colored layer on a polarizing plate.
CONSTITUTION: The diffusion layer 20 is formed on the back side of the 1st colored layer 14 formed by printing on the back side of a polarizing plate 13, and the 2nd colored layer 21 is formed on the back side of the diffusion layer 20. The layer 20 reflects internally light passed through a liqu. crystal cell 11, polarizing plates 12, 13 and the 1st colored layer 14 in a reflection mode and transmits light emitted from a light source 16 for illumination and passed through the 2nd colored layer 21 to the 1st colored layer 14 in a transmission mode. When the thicknesses of the layers 14, 20, 21 are 5W10μm each, fine color display can be carried out in any of transmission and reflection modes.

摘要： PURPOSE:To provide the titled display element which gives positive display with high display contrast and is capable of lowering and steepening threshold value, by adding a dichroic dye, an ionic material and further a specified optically active material to a host liquid crystal having a negative dielectric anisotropy. CONSTITUTION:Substrates 1, 2 are opposed to each other at a given distance therebetween. Each of transparent electrodes 3, 4 is provided on an opposing side of each of the substrates. A liquid crystal 5 is enclosed in a space between the both electrodes. The liquid crystal 5 is obtd. by adding a dichroic dye, an inonic material and further an optically active material to a host liquid crystal having a negative dielectric anisotropy. The opposing surfaces of the substrates 1, 2 are previously subjected to a vertical orientation treatment. Hence, no color is developed when no voltage is applied to the electrodes. When voltage is applied to the electrodes 3, 4, the dipole moment of the liquid crystal molecules is inclined to rotate in the direction of the electrical field, the molecules are revolved by the action of the ionic additive, and the dichroic dye as well as the liquid crystal molecules are brought into a disturbed state. Thus, positive display which has high contrast and is easy to observe from any directions can be obtd. By adding the optically active material, it is possible to steepen threshold value at a low voltage.

摘要： PURPOSE:To prevent coloring while voltage is off and to improve contrast by allowing the dyes having a complementary color relation with the color of the dyes to be added into the liquid crystals of a guest-host type color liquid crystal display element of a positive display to present on the optical path of the liquid crystal cell. CONSTITUTION:Transparent electrodes 2, oriented films 3 as well as mother liquid crystals 4 having negative dielectric anisotropy and dichromatic dyes 5 consisting of red purple dyes are interposed on a pair of glass insulating substrates 1, whereby a guest-host type color liquid crystal display element of a positive display is obtained. Although this display element is blanked out white and is colorless while voltage is off, the element is slightly colored depending upon the conditions of the films 3. In such a case a sheet body 5 colored with the green color having a complementary color relation with the dyes 5 is formed on the surface of the substrate 1. The sheet body may be disposed in any position on the optical path of the display element. By the complementary color of said sheet body, the display element is made colorless while the voltage is off and the display of good contrast from the coloring when the voltage is on is accomplished.

摘要： PURPOSE:To prevent the coloring while voltage is off by forming a light emitting film of roughly the same wavelength as that of the dyes to be added to liquid crystals on the rear surface of one of the transparent insulating substrates of a guest-host type color liquid crystal display element of a positive display. CONSTITUTION:Liquid crystals 4 contg. dichromatic dyes 5 are sandwiched via sealing agents 6 between two sheets of glass insulating substrates 3 formed with oriented films 1 and transparent electrodes 2. Thereafter, a reflection plate 7 of a whitened synthetic resin sheet or thin metallic sheet or the like is provided on the rear surface side of the substrates 3. Here, a thin film 8 of a light emitting material having the emission spectra of roughly the same wavelengths as those of the absorption spectra of the dyes 5 to be added to the liquid crystals 4 is formed on the surface of the plate 7. The absorbancy curve B of this element while the voltage is off is negated by the emission spectral curve D of the material 8, by which coloring is prevented and the image display of good contrast in comparison with the coloring while the voltage is on is obtained.
